IGL@ ou locus lambda da imunoglobulina (também conhecido como IGL^[1] e IGLC6^[2]), é uma região do cromossoma 22 que contém genes para as cadeias leves lambda dos anticorpos (imunoglobulinas).^[3]

O locus lambda da imunoglobulina contém os seguintes genes:

• IGLC@ – grupo constante
  • IGLC1 – imunoglobulina lambda constante 1 (marcador Mcg)
  • IGLC2 – imunoglobulina lambda constante 2 (marcador Kern-Oz-)
  • IGLC3 – imunoglobulina lambda constante 3 (marcador Kern-Oz+)
  • IGLC7 – imunoglobulina lambda constante 7
• IGLJ@ – grupo de união
  • IGLJn – imunoglobulina lambda união n
  • IGLJ1, IGLJ2, IGLJ3, IGLJ6, IGLJ7
• IGLV@ – grupo variável
  • IGLVm-n – imunoglobulina lambda variável n-m
  • IGLV1-36, IGLV1-40, IGLV1-44, IGLV1-47, IGLV1-51, IGLV1-62
  • IGLV2-5, IGLV2-8, IGLV2-11, IGLV2-14, IGLV2-18, IGLV2-23
  • IGLV3-1, IGLV3-10, IGLV3-12, IGLV3-16, IGLV3-19, IGLV3-21, IGLV3-25, IGLV3-27
  • IGLV4-3, IGLV4-60, IGLV4-69
  • IGLV5-37, IGLV5-39, IGLV5-45, IGLV5-52
